Last month banks in China and Korea began disinfecting and isolating used banknotes as part of efforts to stem the spread of the deadly virus.

Ultraviolet light or high temperature is being used to disinfect and sterilise banknotes, before the cash is sealed and stored for up to 14 days before being recirculated, China’s central bank said at a press conference.

A Bank of England source said there were no plans to do the same in the UK.

A Bank of England spokesman told the Telegraph: “Like any other surface that large numbers of people come into contact with, notes can carry bacteria or viruses.

“However, the risk posed by handling a polymer note is no greater than touching any other common surface, such as handrails, doorknobs or credit cards.”

It has been suggested that human coronaviruses can remain infectious on contaminated objects for as long as nine days at room temperature in an analysis of 22 earlier studies of similar viruses, including Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) published online this month in the Journal of Hospital Infection.

However, common disinfectants can swiftly remove them, and they may also be destroyed by high temperatures, the authors wrote. It is not yet clear whether the new coronavirus also behaves in this way.
